Lake Wilhelm was created in 1971 with the damming of Sandy Creek for flood control purposes. Lake Wilhelm is a shallow lake with a maximum depth of about 24 feet at the dam. It has a surface area of 2,800 acres.
Lake Wilhelm is located in Maurice K. Goddard State Park in Mercer County Pennsylvania, about 15 miles west of Franklin, Pennsylvania. The park features natural beauty, wildlife, waterways and public recreational facilities. Lake Wilhelm also borders on Pennsylvania State Game Land.
Birders can watch bald eagles and osprey fish the waters of Lake Wilhelm. Surrounding meadows, fields and forests host bluebirds, purple martins, woodpeckers, woodcocks, nighthawks, snipes, and warblers. Migrating waterfowl such as the loon, common teal, goldeneye, merganser, and bufflehead visit Lake Wilhelm in the spring and fall.
Lake Wilhelm has excellent fishing and ice-fishing. Popular species include largemouth bass, smallmouth bass, walleye, northern pike, muskellunge, crappie, perch, bluegill and catfish. There is an accessible fishing pier. A Pennsylvania State Fishing License is required to fish at Lake Wilhelm.

Sandy Creek, the stream that was dammed to create Lake Wilhelm, was noted in reports made by George Washington during his 1753 trip to Fort LeBoeuf during the French and Indian War. Sandy Creek had a recurring history of flooding. This led to a study by the U.S. Army Corps of Engineers, starting in 1939. Land was acquired in the late 1960s and Lake Wilhelm was formed in 1971. Maurice K. Goddard State Park opened in 1972.
Maurice K. Goddard State park is named for Maurice K. Goddard. once the Secretary of Pennsylvania’s Bureau of Forests and Waters. Goddard’s goal was to have a state park within 25 miles of every Pennsylvanian. When Goddard retired in 1979, he had helped to add 45 state parks and 130,000 acres of state park land to the Pennsylvania State Park system.
